FAUCET.

Specification of Letters Patent.

Patented Mar. i, 1914).

Application filed February 11, 1909. Serial No. 407,296.

1 '0 all whom it may concern:

Be it known that I, CARL BARR, a citizen of the United States, andresiding at Ohicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Faucets, of which the followingis a complete specification.

This invention relates to improvements in faucets and more particularlyto a self closing faucet of that class having a fluid control fortheclosing movement of the valve.

The main objects of this invention are to greatly simplify theconstruction of self closing faucets, and to provide a faucet which isso constructed that when the parts governing the closing operation areremoved for inspection or repair the valve will remain in closedposition and prevent the fluid from escaping, and thereby avoid thenecessity of removing the faucet from its connection or shutting off thefluid below the faucet.

The invention consists of the matters hereinafter described in thespecification and more fully pointed out and defined in the appendedclaims.

In the drawings: Figure l is a vertical .sec tion of a faucet embodyingthis invention. Fig. 2 is a side elevation of the same.

As shown in said drawings: A indicates a faucet body havinga fluidchamber a; therein, and beneath said chamber and opening thereinto is athreaded tube section a adapted to be connected with the source of fluidsupply. Adjacent the opening from said tube section into said chamber isa valve seat a and a valve closure B is adapted to seat thereagainst andopen outwardly from said chamber. The valve stem f extends upwardlythrough the top a of said chamber into a controlling cylinder O which isformed on the upper portion of the body, and a piston b is rigidlysecured thereon and fits loosely in said cylinder so that fluid may passaround the same. Mounted 011 said stem between said piston and the top aof the fluid chamber is a coiled spring 5 adapted to normally hold thevalve closure against its seat and thereby prevent the passage of fluidtherepast. Removably secured on the top of said cylinder is an aperturedhead or cap O, and extending therethrough is a pushrod c which is inaxial alinement with said stem. On the outer end of said stem is a pushbutton 0 and on the inner end thereof is a flange 0 adapted to limit theoutward movement of said rod. Secured in the inner end of said rod is abolt 0", and secured to the inner end of said bolt is a flexiblediaphragm a of any preferred material, such as rubber or metal. The edgeof said diaphragm rests on the top of said cylinder on said edge and isheld in close contact therewith by means of the cap O.

The operation is as follows: \Vhen the push rod is depressed or forcedinto the cylinder the inner end of the bolt 0 contacts with the end ofsaid valve stem and forces the valve closure away from its seat. hen thevalve is held open, fluid may pass into the cylinder about the stem andpass around the piston into the space next to said diaphragm. When thepush rod is rcleased the dia ohra m forces it back to nor mal position,and the spring acting on the piston Z)" closes the valve, but itsclosing is retarded by the passage of the fluid back past the piston Z).The diaphragm effectively closes the cylinder, and inasmuch as the valveis held against its seat by the spring, the cap and the diaphragm may beremoved without shutting off the fluid be low the faucet.

Obviously a faucet constructed in accordance with this invention affordsa very simple construction and one in which the valve controllinmechanism is removed from the path of the fluid. Obviously also manydetails of form and construction may be varied without departing fromthe principles of my invent-ion.

I claim as my invention:

1. The combination with means affording a fluid chamber, of a valvecontrolling the admission of fluid thereto, a cylinder ad jacent saidchamber, and adapted to receive fluid therefrom, a piston in saidcylinder adapted to control the closing of said valve, a diaphragmacross said cylinder adapted to be moved independently of said piston,and means thereon adapted to open said valve.

2. The combination with a faucet body of a valve therein, a cylinder onsaid body and adapted to receive fluid therefrom, a stem on said valveextending into and terminating in said cylinder, means on said stemadapted to normally close the valve, a piston 011 the stem adapted toretard the closing of the valve, a pushrod extending into said cyland awasher 0" is placed inder, and a flexible diaphragm connected therewithand adapted to move upwardly independently of the piston.

3. The combination With a faucet body of a valve controlling the passagetherethrough, a cylinder on said body, a flexible diaphragm therein andproviding a closed partition across the same, fluid controlled meansbeneath said diaphragm adapted to control the closing of the valveindependently of the movement of said diaphragm, and means connectedwith said diaphragm adapted to open the valve.

4. The combination with a faucet body of a valve controlling the passagetherethrough, a cylinder on said body and adapted to re ceive fluid fromsaid passage, a stem on said valve extending into and terminating insaid cylinder, a piston on said stem fitting loosely in said cylinder, aspring on the stem acting normally to hold the valve in closed position,a flexible diaphragm extending across said cylinder above said stem andout of contact therewith, and a push rod slidably mounted in saidcylinder in axial alinement with said stem and connected to saiddiaphragm, said diaphragm being adapted to return to normal positionindependently of said piston.

5. The combination with a valve body having a fluid chamber therein, ofa valve seat at the entrance to said chamber, a valve closure therefor,a stem on sald closure extendlng into and terminating in said cyl1nder,a piston on said stem, a spring on said stem engaging said piston andthe bottom of said cylinder, a flexible diaphragm in said cylinder andout of engagement with said stem, and means thereon adapted to operatesaid valve.

6. The combination with a faucet body having a fluid chamber therein, avalve controlling the entrance to said chamber, a cylinder on said bodyand adapted to receive fluid from said chamber, a cap on said cylinder,a diaphragm engaged between said cap and cylinder, a stem on the valveextending into said cylinder and terminating beneath said diaphragm, apiston on said stem, a spring beneath the same adapted to normally holdthe valve in closed position, and a push rod for said stem slidably en.-gaged in said cap and connected to said diaphragm.

In testimony whereof I have hereunto subscribed my name in the presenceof two witnesses.

CARL BARR.
